1230 The Trees of Great Britain and Ireland 



trees, one near the Pagoda which is divided into two main stems, and measured 85 ft. 

 by 7 ft. 9 in. in 1909 ; the other near the pond is a much more spreading and thicker 

 tree, and now measures about 55 ft. by 1 1 ft. At Arley Castle there is a healthy tree 

 free from branches to about 30 ft. up and measuring 70 ft. by 5 ft. 9 in. At Cobham 

 Park there is a fine tree of the same type 86 ft. by 8 ft. 10 in. At Croome Court, 

 Worcestershire, there is a tree grafted on the common oak, 65 ft. by 6 ft. 5 in. At 

 Nuneham Park, Oxon, another was in 1906, 60 ft. by 8 ft. 3 in. At Barton, Bury 

 St. Edmunds, a slender tree measured in 1908, 64 ft. by 4 ft. 2 in.; at Ampton 

 Park, Suffolk, another, measured by Henry in 1909, is 40 ft. by 5 ft. 10 in. At 

 Glendurgan, Cornwall, Mr. A. B. Jackson measured a thriving tree, 40 ft. by 4 ft. 

 2 in. in 1908. In the Knaphill Nursery, near Woking, there are two specimens 

 of moderate size. I have also seen specimens at Milford House, near Godalming, 

 and at West Dean Park. 



In Scotland we know of no tree of this species; but in Ireland, at Fota, there 

 is a thriving specimen, 45 ft. by 5 ft. 4 in. in 1907. (H. J. E.)

A tree, attaining in America 50 ft. in height and 5 ft in girth, but usually 

 smaller. Bark about an inch thick, dark brown or nearly black, divided into small 

 square scaly plates. Young branchlets slender, coated with white stellate tomentum, 

 most of which disappears in the course of the summer. Buds minute, ovoid, obtuse, 

 chestnut brown, glabrous. Leaves (Plate 339, Fig. 72) deciduous, membranous, 

 2 to 3 in., occasionally 5 in. long, \ to f in. broad, oblong-lanceolate, rounded or 

 cuneate at the base, acute or rounded and with a bristle at the apex, entire and 

 undulate in margin ; upper surface dark green, shining, glabrescent ; lower surface 

 coated with thick greyish-white tomentum, disappearing in part in summer ; petiole 

 about \ in. long, tomentose. 



Fruit ripening in the second year, sessile or shortly stalked ; acorn ovoid, about 

 \ in. long, hoary pubescent at the apex ; cupule variable in shape, saucer or cup-like, 

 pale pubescent within, and covered externally by thin imbricated ovate tomentose 

 scales. 



This species, 1 which appears^ to be a variety of Q. Phellos, adapted by its 



1 Q. pumila, Walter, which resembles this species, is shrub'by in habit, ripens its acorns in one year, and is practically 

 evergreen, carrying its leaves until the new ones appear in the following spring. Cf. Sargent, Silva N. Amer. viii. 115, 

 t. 404 (1895).
